Short summary

This study presents the latest version of the global ozone reanalysis product developed at Cerfacs. The reanalysis is based on the assimilation of satellite data from the Infrared Atmospheric Sounding Interferometer (IASI) in the Météo-France chemical transport model. The results show that the quality of the ozone fields is comparable to current state-of-the-art systems and suggest that IASI provides useful information for ozone reanalyses, especially in the upper troposphere.
